Process for producing tetrakisfluorophenylborate

摘要

A process for preparing a tetrakisfluorophenylborate which is useful as a catalyst component for the polymerization of olefins or as a raw material for synthesizing the same, efficiently at a high productivity per unit amount of a solvent and at a high yield.

The tetrakisfluorophenylborate is dissolved in a solvent with a SP value of 15 ≤ SP ≤ 30 and deposited from water or an aliphatic hydrocarbon solvent.
